Protect the design of the control system and study in intelligence of the database
Abstract :This thesis further investigates operation principle of the AT89 series one-chip computer , the characteristic and range of application. Suddenly lost electrical power to the library database, working environment temperature rise , incessant power (UPS ) electric consumption reason such as being insufficient and cause database magnetic disc array damage question and phenomenon this, have carried on the analysis and research, regarded one-chip computer as and controlled the magnetic disc array intelligence of the central database and protected the control system after designing one kind, carry on effective protection to the magnetic disc array of the database .We have used procedure special-purpose serial communication controlling RS-232-C controlling part, realize control system and database control communication, PC of host computer.
The prototypes of a machine developed are through the experiment of debugging, operation stability , result are good, have achieved the purpose that specification requirement and intelligence protect of designing. This subject is finished together by student Xie RenShui and me.
